BACKGROUND

The recent onset of the Covid-19 pandemic has made apparent a rapid and accurate detection of infection is needed for early treatment and analysis of the rate of spreading of the infections. The rapid and accurate detection of infection is also needed for other known infectious viruses and bacterial pathogens and new infectious viruses and bacterial pathogens that may appear. Initial testing was slow and confined to a small number of laboratories using processes that in many cases took days to complete. What is needed for rapid detection for treatment and to collect ample data to locate and measure the rates of infection is a broader range of application venue availability outside of laboratories and a range of training needed to perform the detection testing.
